Abstract
A shutter arrangement for closing an aperture formed in the fixed leading edge of an aircraft wing when a track supported slat moves from a stowed, cruise configuration in which it lies adjacent the fixed wing portion to a high light configuration in which it is spaced from the wing to define a slot. The aperture, which exist to accommodate the slat to track attachment `knuckles`, may induce undesirable flow disturbance in the slot formed between the slat and the fixed leading edge. The present invention provides a hinged retractable shutter for closing off the aperture when the slat is deployed. In the preferred arrangement the shutter is of multi-panelled hinged configuration and, in one described arrangement is of one-piece moulded composite rubber construction.
